DEVICE FOR DISPENSING LIQUID SOAP, 8w.

' a specification.

This invention relates to a device for dispensing hquids and. more particularly to a device for dispensing liquid soap.

It is the object of this invention to provide a dispensing device of this character which is comparatively simple and inexpensive in construction, which can be applied to bottles of ordinary construction, which is convenient in operation and which efiectually prevents the liquid in the bottle from evaporating when the device is not in use.

supporting arm 8. formed on one section of .the clamping collar and adapted to be secured by screws or otherwise to a suitable support. The sections of the clamping collar are detachably connected so as to permit of introduclng or removing the bottle therefrom, this detachable connection consisting preferably of a hinge 9 which pivotally connects one pair of corresponding ends of the clamping collar,- and a clamping screw 10 cornecting the other pair of corresponding en s. 4

11 represents an uprightouter valve tube arranged vertically within the bottle, reservoir or tank and terminating at its u per end above the liquid level in the bottle while lts'lower end terminates below the lower end of the neck thereof. Near its lower end and within the bottle. the outer or fixed valve tube is provided with a liquid discharge port or outlet opening 12.

Slidable vertically or lengthwise within the outer valve tube is an inner movable valve tube 13 which terminates at its upper end above the upper end ofthe outer tube while its lower end terminates below the ing the form of a pear-shaped knob secured to the lower end/of the inner tube and forming a shoulder thereon which is adapted to engage with the lower end of the outer tube and limit the ascent of the inner tube. Near itslower end the inner valvetube is provided with a'liquid outlet port or discharge opening 16 which is adapted to register with the liquid discharge opening of the outer tube when the inner tube is raised to its highest position and thereby permit the escape of liquid through said ports, said inner discharge port 16 being moved downwardly and outof register with the outer port 12 when the inner tube reaches its lowermost position, thereby cutting off the escape of liquid from the reservoir or bottle in this position of the inner tube. The inner and outer tubes are held against turning relatively to each other but are free to slide one upon the other for the purpose of bringing their liquid outlet ports into or out of register but preventing the same from becomthe inner tube the same is provided withone or more air inlet openings or ports 19 which in the ralsed position of this tube are carried above the upper end of the outer tube and thus permit air to pass from the inner tube into the reservoir above the liquid, while upon lowering the inner tube the air ports are carried downwardly within the bore of the outer tube and closed.

The discharge of the liquid from the reservoir and the admission thereto of air above the liquid preferably takes place in the weighted handle or knob at the lower end of the inner tube. For this purpose this handle is provided with an air inlet passage 20 which opens at its outer end at the side of the knob while its inner end opens into the lower endof the inner valve tube adjacent to one side of the bore thereof and this handle is also provided with a liquid discharge passage 21 which opens at its outer end on the convex underside of the handle on one side of its center while its 'inner end terminates centrally relatively to the inner valve tube. and at the lower end thereof. Communication is established between the inner end of the discharge passage and the inner discharge port 16 by means of a branch pipe or tube 22- arranged axially or concentrically within the inner valve tube and bearing at its lower end against the upper end of the handle so as to communicate with the liquid discharge passage 21 while its upper end is provided with 'a lateral turn whereby the same communicates with the inner liquid discharge port 16, as best shown in Fig. 1. The weight handle is preferably secured to the lower end of the inner vah'e tube by means of an internal screw threaded socket 23 arranged at the upper end of this handle and receiving the lower externally screw threaded end ofthe inner valve tube. A tight joint is produced between the lower end of the branch-tube and the handle by tapering the lower end of this branch tube and engaging the same with a correspondingly shaped seat of the bottom of the socket in said handle. It follows from this construction that the handle may be screwed tightly upon the lower end of the inner valve tube and brought firmly into engagement with the branch tube'22 without requiring any special care for this purpose in the manufacture and assembling of these parts and'still insure.communication between the branch tube and the discharge passage and communication between the interior of the inner valve tube and the air inlet passage of the handle.

In the normal position of the handle and inner valve tube these parts are lowered by gravity thereby shutting ofi communication between the discharge'ports 12, 16 and clos ing the air inlet port 19, whereby the admission of air into the reservoir above the liquid is prevented and the escape of liquid from the reservoir is likewise prevented.

When it is desired to obtain a quantity of the liquid from the reservoir the palm of the hand is placed against the underside of the handle and the latter is pressed upwardly by the hand until the inner valve 'tube reaches its highest position.

When this occurs the air inlet port at the upper end of the inner valve tube is uncovered and the external atmosphere is permitted to pass successively to the air passage in the handle, the conduit within the inner valve tube and the outlet port of the inner. tube into the reservoir above the liquid, thereby permitting the liquid to escape from the reservoir through the discharge ports 12, 16, branch tube 22 and delivery passage in the handle to the palm of the hand which has raised the handle. When suflicient liquid has been discharged in this manner the handle and associated parts are permitted to drop by gravity, thereby closing the air port at the top of the inlet tube and moving the discharge ports out of-registen with each other, whereby the outflow of liquid from the reservoir is arrested.

Various means may be provided for mounting this valve mechanism within the bottle. The means shown in Figs. 1, 2, 3 and 4 are designed more particularly for applying this dispensing device to a bottle which has no cork. The means for supporting the valve mechanism shown in. Figs. 1 to i are constructed as follows: 24 represents a supporting tube or sleeve which receives the outer valve tube and is arranged in an upright position within the bottle. This supporting tube terminates at its lower end below the lower end of the neck of the bottle while its upper end terminates below the upper end of the outer valve tube. Near its lower-end this supporting tube is provided withadischarge opening 25 which registers withthe discharge port 12 of the outer valve tube. On diametrically opposite sides of the supporting tube and within the-bottle the same is provided with two clamping or coupling arms 26 which bear at their outer extremities against the interior of the breast of the bottle; These arms are so constructed and attached to the supportsame through the neck of the bottle and introducing the same into the body of the isa-mi -bottleand thereafter the clamping armsmay be spread so asto project laterally from the supporting tube and engage with the inner side of the breast of the bottle.

For this purpose each of the arms is preferably constructed of U-form and its legs are pivotally connected at their ends with his ' outer end of the neck of the bottle A liquid opposite sides of a laterally projecting lug 2 on the supporting tube by means 'of ahorizontal pin 28. "These coupling or clamping arms are free to swing downwardly or outwardly against opposite sides ofthe supporting tube so asfto permit'of' passing them .with the tube through the neck of the bottle into the body of'the' same and after. these arms'have passed inwardly beyond the breast of the bottle the same are turned outwardly into a position at right angles to the supporting tube, their movement in this direction being limited by.

means of heels 29 formed on the coupling arms and bearing against the shoulders 30 on-the adjacent part of-the supporting tube.-

In their extended .position the clamping or coupling arms engage by'their outer ends with the breast of the bottle and are held in this position by an outward pull on the supporting tube which is preferably pro duced bya screw nut 31 applied to the externally screw threaded outer end of the supporting tube and bearing. against the tight-joint is produced between this screw nut and the neck of the bottle by means of;

a packing disk or washer 32 of cork or simi- -lar material which is interposed between the screw; or clamping nutand the neck of X the bottle, whereby the same also serves as a closure for this neck-which effectually prevents leakag f The lower end ofthe supporting tube is provided with one or more notches 33," as

shown in Fig. 4, so as to permit of applying a key or wrench to the supporting sleeve forholding the same against turning while the clamping screw is turned thereon.

7 suitable packing material 7 may be intertube, as shownin Fig. 1, so as-to prevent leakage of liquid or air. through the joint posed between the bore of the supporting tube and the-peripheryof theouter valve between the same. I

If desired, the supporting: tube'and'outer valve tube may be constructed in one piece instead of being made of separate pieces, as shown in Fig. l. V

In the construction shown in Figs. :5 and 6,.the outer-valve tube is passed through a central opening forme d 'in a, stopper 35 of cork which closes the neck of the bottle and a tight joint is produced between the outer valve tube and this cork. by means. of a clamping disk 36 applied to an external screw thread on the lower end ofthe outer tube and bearing against the outer end of thecorle- When shipping this liquid dispensing device in an assembled condition with a bottle containing a charge of liquid it is desirable to closethe liquid discharge and the air inletof the same so as to prevent the escape of liquid and'drying outof the same. For

thispurposethe handle is unscrewed from the inner valve tube during transportation or storage and a cap 37 is screwed over the which covers the lower end of the branch liquid tube. and the inner valve tube'fas' shown in Fig.8. The outer-side 'of-this cap is also preferably pointed or tapered to .a

sharp point, as shownat 39in Fig. 8, so that the same may beused as a tool for boring a hole in the cork of a bottle for receiving the valve mechanism incase the dispensing de'-- vice is put uponthe marketjindependently of a bottle.

. lit will be noted that-this device promotes cleanliness and reduces the liability of transmitting contagious diseases from 'on e person to'another toa mlmmuin when used for dispensing liquid soap, inasmuchas each person only withdrawsras much soapfrom the reservolr as-1s.req u1red for personal use.
